摘　　要：以前期开发的双燃料汽车闭环电控单元(ECU)为对象,介绍了一套在线修改与存储控制参数的系统,此系统利用PC机与单片机进行串行通讯,使得ECU在配车实验时可以实时调试控制参数,并将调试好的参数以串行方式存储到EEPROM.此系统还有监视功能,对系统稍做修改后,还可用于其他控制系统.A system of on-line modifying and storing control parameters is introduced based on the close-loop electronic control unit(ECU) for dual-fuel automobile. This system makes use of the PC with singlechip to proceed the serial communication, so that during the practice test the control parameters in the ECU may be adjusted in time, and those ones which have been adjusted will be stored in the serial EEPROM. Besides, the system shows you the function of surveillance,and after slightly modifying the express, it can also be used for another control system.
